To all whom it may concern.'

`Be it known that I, CLAUDE A. BARNES, a citizen of the` United States,residing at Rolling Prairie, in the county of Laporte and State ofIndiana, have invented a new and useful FreightCar Door, of'which thefollowing is a specification.

The invention relates to improvements in freight car doors.

The object of the present invention is to improve the construction offreight car doors, and to provide a simple, eilicient and comparativelyinexpensive vcar door, designed for use on the exterior of box cars,stock cars and the like, and capable of affording a stornrproof closureof great strength and durability.

A further object of the invention is to provide va 'pivotally mountedcar door of this character, adapted when unlocked to swing toward itsopen or closed position through gravity, whereby the door may be easilyoperated and readily moved to either its open or closed position with.little effort. With these and other objects in view, the inventionconsists in the construction and novel combination of parts hereinafterfully described, illustrated in the accompanying drawing, and pointedout in the claims hereto appended; it being understood that variouschanges in the form, proportion, size and minor details of construction,withinthe scope of the claims, may be resorted to without departing fromthe spirit or sacrificing any ofthe advantagesbf the Ainvention.

In the drawing :-Figure l is an' elevation of aV portion of a freightcar provided with a door, constructed in accordance with this inventionand shown closed. Fig. 2 is a longitudinal sectional view of the same,the

door being open. Fig. 3 is a detail sec* tional view on the line 3 8 ofFig. l. Fig. 4 is a detail sectional view on the line 4 4: of Fig. l.

Lil". numerals of reference designate corresponding parts in all thefigures of the drawing. n i l Q In the accompanying drawing in which 1sillustrated the preferred form of the invention, l designates a freightcar door pivoted at its upper rear corner by a horizontal bolt 2, orother suitable fastemng device, and arranged to swing backward andforward to uncover the door opening 3 of a car 4.- and to cover or closethe same. The pivoted door, which is arranged on the exterior of the carIl, is adapted to swing by' gravity nearly to its open or closedposition, and it requires but little effort to complete the opening orclosing movement of the door, which is locked in its closed and openpositions by front. and rear catches 5 and 6 to prevent it from swayingor oscillating or projecting below the bottom of the body of the carwhen it is unfastened; The door l is provided at its upper rear cornerwith a hinge element T, constructed of suitable metal and having an eyeor opening to receive the pivot bolt 2, and provided with. integralmetallic straps or braces 8, divergving downwardly and forwardly fromthe upper rear corner of the door when the latter is closed, and securedat intervals to the door and adapted to brace and reinforce the same toprevent the door from sagging. The door is also reinforced at its upperpivoted corner by a metallic binding strip 9, suitably secured to thedoor and arranged in flush rela-tion with the adjacent edges of thesame. The bolt is supported at its outer end by a hanger or bracket l0,constructed of suitable metal and consisting of an intermediatedepending portion and terminal attaching portions ll. The intermediatede pending portion is preferably in the form of a loop, and is providedat the bottom with a central opening l2 through which the pivot boltpasses. The attaching portions ll are secured by suitable fasteningdevices to an over-head guard 13, which receives the upper edge of thedoor l.

rl`he guard consists of a bar or member il, extending longitudinally ofthe car above the plane of the door opening and project ing downward andprovided at its lower edge orfaoe with a strip, extending below the baror member 14 and forming a depending tlange at the outer face of thedoor, as clearly illustrated infFig. 3 of the drawing. The over-headguard is of sufficient length to receive the door when the latter is inits open position. The car is provided around the door opening with arectangular door, and it has a curved guide or brace 16,

lextending upwardly and/rearwardlyfrom larlyA related vportions andprovidedA at 'the `angle with an l exteriorA enlargementV- '18,

rounded to present an 'outer curved face andA -having terminal engagingfaces or shoulders 19 and 20, adapted to engage withthe catches A5 and6,`whereby the door is locked inv its closed and open positions. The

. i corner iro catche"` 5 and 6= which are constructedyofv suitablespring` material, are secured vto front and rear vertical bars 2l and22'and cons-1stof vertical portions and lower en gaging portions 23,arranged at an angle-to the vertical portions-and sigmoidally curved,

as shown, to lprovide an inner. concave por# f tion to tit the roundedenlargement of the catch automatically. The engagingportion '23 isprovided-at an intermediate point a shoulder QA, preferably formed,byenlargi ing the terminal ofthe catch. W enA the door isopened orclosed, the roun ed portion of the corneriron lof the door is car-vvried into contact 'with the free terminalv portion of one fof-thecatches, whichcatch is moved backwardly jor outwardly away from thedoor'until'the rounded-portion passes the 'shoulder of the catcl,j when.the
